Gravitational Effective Theories with Maximal Supersymmetry and a Peculiar Parity
Justin Berman, Simon Caron-Huot, Aditi V. Chandra +4
The paper investigates possible four‑dimensional UV completions of maximally supersymmetric (𝒩=8) supergravity by imposing tree‑level factorization and a special “peculiar parity”…
String Theory from Maximal Supersymmetry
Henriette Elvang, Aidan Herderschee, Roger Morales
We explore the space of non-gravitational, maximally supersymmetric, planar 4d effective field theories (EFTs) that have super Yang-Mills (SYM) at leading order. In…
The spectrum of Feynman-integral geometries at two loops
Piotr Bargiela, Hjalte Frellesvig, Robin Marzucca +4
We provide a complete classification of the Feynman-integral geometries at two-loop order in four-dimensional Quantum Field Theory with standard quadratic propagators. Concretely,…
Classification of Feynman integral geometries for black-hole scattering at 5PM order
Daniel Brammer, Hjalte Frellesvig, Roger Morales +1
We provide a complete classification of the Feynman integral geometries relevant to the scattering of two black holes at fifth order in the post-Minkowskian (PM) expansion, i.e. at…
Special Functions and Geometries in Scattering Amplitudes: From Particle Physics to Gravity
Roger Morales
This thesis focuses on the fields of scattering amplitudes and Feynman integrals, with an emphasis on the geometries and special functions that they involve, and is devoted to two…
Calabi-Yau Feynman integrals in gravity: -factorized form for apparent singularities
Hjalte Frellesvig, Roger Morales, Sebastian Pögel +2
We study a recently identified four-loop Feynman integral that contains a three-dimensional Calabi-Yau geometry and contributes to the scattering of black holes in classical gravit…
